### Alcubierre drive

**Alcubierre metricwarp driveAlcubierre drives**

It is used in certain speculative theories, such as on the construction of artificial wormholes and the Alcubierre drive.

The proposed mechanism of the Alcubierre drive implies a negative energy density and therefore requires exotic matter.

### Wormhole

It is used in certain speculative theories, such as on the construction of artificial wormholes and the Alcubierre drive.

Wormholes that could be crossed in both directions, known as traversable wormholes, would be possible only if exotic matter with negative energy density could be used to stabilize them.

### Time travel

**time machinetime-traveltime-traveling**

Because time travel is considered to be non-physical, tachyons are believed by physicists either not to exist, or else to be incapable of interacting with normal matter.

According to current theories on the nature of wormholes, construction of a traversable wormhole would require the existence of a substance with negative energy, often referred to as "exotic matter".

### Faster-than-light

**faster than lightFTLsuperluminal**

In this way, the negative mass of exotic matter is now associated with negative momentum, negative pressure, negative kinetic energy and FTL (faster-than-light).

Mechanical equations to describe hypothetical exotic matter which possesses a negative mass, negative momentum, negative pressure, and negative kinetic energy are

### Energy–momentum relation

Using these above equations, the energy-momentum relation should be

By contrast, the hypothetical exotic matter has a negative mass and the energy–momentum equation is

### Negative energy

**negative kinetic energynegativenegative energies**

In this case, it is unnecessary to introduce a negative energy because the mass can be negative although the energy is positive.
